The paper presents the preliminary result of the development of the eDPP (enhanced Dynamic Path Predictor) during overtaking situations. The eDPP application offers a higher degree of accident prevention through: advanced driver-information and driver-warning strategies; improved actuation using the new and enhanced ADASIS v2 (Advanced Driver Assistance Systems Interface Specifications, version...

An often-ignored aspect of unmanned cross-country vehicles is the dynamic response of the vehicle on different terrain. We discuss techniques to predict the dynamic vehicle response to various natural obstacles. This method can then be used to adjust the vehicle dynamics to optimize performance (e.g. speed) while ensuring that the vehicle is not damaged. This capability opens up a new area of o...

In the paper, a mathematical model assembling a "driver-mobile vehicle-road environment" system and capable of simulating the process of mobile vehicles skid in traction movement mode is proposed. The usage of non-linear drift models allows the development of efficient algorithms for mobile vehicles dynamic stabilization systems. INTRODUCTION The traction loss between the vehicle and the road a...

To design an automatic steering controller with high performance for autonomous vehicle, it is necessary to have a precise model of the lateral dynamics with respect to the steering command input. This paper presents an empirical modeling of the steering system for an autonomous vehicle. The steering system here is represented by three individual transfer function models: a steering wheel actua...

Conventionally, the well known position-velocity-acceleration (PVA) model is adopted as the dynamic model of Kalman filter for GPS positioning. However, as a moving vehicle corners at faster speeds, the conventional PVA model without using extra sensors can no longer be adequate for describing the motion of the vehicle. Thus, the positioning result of the vehicle will be less accurate, and norm...

Advances in motor vehicle engineering will allow greater refinement of the dynamic qualities of passenger cars in the near future. This paper describes the development and initial validation of a reliable and valid multidimensional scale to assess these parameters based upon a technique previously developed to evaluate aircraft handling qualities. The scaling methodology developed emphasizes th...

Vehicle trajectories contain rich information on microscopic phenomena such as car following and lane changing. Despite many efforts to retrieve reliable trajectories from video images, previous approaches do not give high enough quality of trajectories that can be used in microscopic analysis. We introduce a new vehicle tracking approach based on a model-based 3-D vehicle detection and descrip...

The long term goal is development and utilization of a comprehensive (broadly capable) marine particle analysis system. The system is designed with wide dynamic range, thus, it will ultimately be used for high speed, high resolution characterization of water column particle fields in high, medium and low latitudes. As part of a broader goal this project continues advancement of the AOSN concept...

A project concerned with applying Dynamic Data Driven Application Simulations (DDDAS) to monitor and manage surface transportation systems is described. Building upon activities such as the Vehicle-Infrastructure Integration initiative, a hierarchical DDDAS architecture is presented that includes coupled in-vehicle, roadside, and traffic management center simulations. The overall architecture i...

Performing physical acceptance tests of an Unmanned Ground Vehicle (UGV) can be expensive and time-consuming. This paper discusses simulation-based acceptance testing and failure analysis for UGVs. Both dynamic and static simulation models are developed. A systematic statistical testing approach is presented to quantitatively assess when a simple static simulation model can be used to approxima...
